A shopping cart that critically injured two men might have been used as a weapon in a dispute between taxi drivers competing for fares outside a New York City shopping center, according to a taxi driver representative.

Louncey Camara, 52, and Ibrahima Sagne, 30, were hit after the cart plummeted three stories at Mott Haven Mall in the Bronx.

"It's about who took whose passenger, and who was waiting for who, and whether you can really pick them up or not pick them up," Fernando Mateo, president of the New York State Federation of Taxi Drivers, told WABC of the brewing battle between licensed and unlicensed cabbies.

The New York Police Department said it is reviewing surveillance video of the incident in order to determine what happened.

Camara suffered lacerations and a puncture to his forehead and Sagne had lacerations to an eye and the back of his head.

"It was pretty bloody," Julie Russ, a cashier at a Home Depot in the shopping center told the New York Daily News. "They were laying on the ground. One guy was trying to sit up, and the other guy was just laying there. He wasn't moving."

This is the second time in three months that a shopping cart has been pushed from a higher floor and landed on a shopper.

Marion Hedges, 47, went into a coma after two boys pushed a shopping cart from a fourth-four parking garage in New York City Oct. 30, 2011. Hedges had been shopping for Halloween candy to donate to charity at the time she was hit.
